IMPROVEMENT IN METAE ROOFING.

Specication forming part of Letters Patent No. 219,954, dated September 23, 1879; application filed June 23, 1879. v

To all 'whom it may concern.:

Be it known that we, ROBERT J ONEs and LEWIS S. BoNBRAcK, of Waynesburg, in the county of Stark and State of Ohio, have invented a new and useful Improvement in Metal Roofing, of which the following is a specification.

This invention relates to that class of metal roofs inwhich the edges of the metal plates are turned up to form anges, and are then bent over each other so as to form a cap and produce a close and water-tight joint.

It consists of an anchor provided with a short and a long prong, so arranged that the short prong is bent over the ange of one of the roof-plates, and the long prong is passed through and passed over the flange of the ad- 'joining plate. The iiange of the latter plate is then bent down and over the iiange of the first plate, so as to form the cap of the rolljoint.

In the accompanying drawings, Figure 1 is a vertical cross-section and perspectiveview of the roll-jointl before the iianges are bent over each other. Fig. 2 is a vertical crosssection and perspective view of the roll-joint in the same position, and having a piece of felt or like material inserted between the adjoining iianges. Fig. 3 is a vertical cross-section of the joint, showing one flange bent ldown over the other. Fig. 4-shows the same vertical section with an additional cap or hood. Fig. 5 shows the additional cap or hood.

Similar letters of reference indicate corresponding parts.

A is the sheeting, upon which the metal plates B and O, provided with flanges D and E, having different heights, are attached. A cleat or anchor, H, provided with a long prong, L, and a short prong, K, is attached to the sheeting, so that it will be between the two anges D and E. The-smaller prong, K, is ,bent over the edge of the lower iiang'e, D, thus securing the plate B, andthe larger prong, L, is first passed throughthe slot M in the higher flange, E, and is then bent over the top edge of this fiange, as is shown in Fig. nl. The higher flange, E, is then bent down over the edge of the lower iiange, D, as is shown in Fig. 3, and forms the cap of the roll-joint.

In case the joint is very much exposed and liable to become leaky, an additional cap, P, can be attached to the same. The edges of the cap P are folded, as is shown in Fig. 5, the fold S being much larger than R. Y If the cap they to be-applied the fold S is passed over the upper edge of the liange E 'when the same is in the position shown inFig. 1, and the cap is then bent down over the edge of the liange D with, the Bange E, as shown in Fig. 4. The fold S is turned down on the side ofthe ange E. The edge of the cap is folded `so that no rough edges are presented. This cap I). covers.

all the slots M through which the long prongs ofthe anchors pass, and produces a perfectly close and tight joint. This cap may be applied throughout the whole length of the joint, or only at the anchors.

` A packing-strip, F, of felt, tarred paper, or some other suitable material, maybe applied between the two flanges, if desired. It is of the same height as the larger flange, E, is placed alongside of it, pierced, and secured to the flange by the prong L, as is shown in Fig. 2, and with this {iange is bent down over the fiange D, as is shown in Figs. 3 and 4.' The additional cap is attached in the same manner as before. The whole joint may be laid down dat, if desired.

Having thus described our invention, `We claim as new and desire to secureJ by Letters Patent- 1. In a roll-joint of a metal roof, the anchor H, having a short prong, K, bent over the flange of one plate, and the long prong, L, passing through and over the edge of the flange of the other plate, as and for the purpose set forth. A

2. The combination of the prong L and flange E, the former passing through the latter and turned around it, as set forthto form a cap and economize the metal. f

3. In a roll-j oint of metal roofing, a packing, F, secured to iiange E by the prong L, passed through and over the upper edge of both, as shown and described.

4. The combination, with anchor H, having short prong K and long prong L, of the short iiange D, long iian ge E, and intermediate package F, as and for the purpose specified.
